Specification of Letters Patent. Patentedtlune 2Q}, 1915 Application filed March 1, 1915. Serial No. 11,167.

To all whom it may concern Be it known that I, HERBERT F. MILLER, a. citizen of the United States, residing at WVollaston, in the county of Norfolk and State of Massachusetts, have invented certain new and useful Improvements in Lamp- Burners, ofwhich the following is a specification, reference being had to the accompanying drawings, forming part thereof.

This invention has reference to improvements in lamp burners in which tubular wicks are used and the invention resides particularly in the means for carrying and operating the wick.

The object of this invention is to so construct a carrier for the tubular wick of an Argand burner (so called) for lamps that a much greater length of the wick can be utilized than where the wick carrier has but one point at which the wick can be attached and where said wick carrier has a limited movement.

Another object of the invention is to provide a wick carrier for Argand burners having means for detachably engaging a wick whereby relative adjustment may be effected between the wick and its carrier from time to time.

Other objects of the invention will appear from the following description.

The invention consists in the improved wick carrier.

The invention also consists in such other novel features of construction and combina tion of parts as shall hereinafter be more fully described and pointed out in the claims.

Figure 1, represents a vertical transverse sectional view of the improved lamp burner taken on line 11 Fig. 3. Fig. 2, repre: sents the improved wick carrier in enlarged elevation, the operating device being shown in relation thereto. Fig. 3, represents a plan view on enlarged scale of the burner, portions thereof being shown in section as on line 33 Fig. 5. Fig. 4:, represents an enlarged detail view of a. portion of the carrier. Fig. 5, represents a sectional view, of parts of the wick carrier, taken on line 1-1 Fig. 3. Fig. 6, represents a plan view of portions of the wick carrier showing details of construction.

Similar character of reference designate corresponding parts throughout.

1n carrying this invention into practice my object has been to provide a wick carrier adapted to move a greater distance than those heretofore employed whereby a greater length of the wick can be progressively advanced, as consumed, to the point of combustion.

Another important feature of my invention is to utilize a greater length of the wick, than has heretofore been possible, by so constructing the wick carrier that, from t me to time, the wick can be advanced relative to said carrier and again secured to said carrier.

As shown in the drawings in its preferred form 7 indicates the font or oil container of a lamp adapted for use with an Argand burner and provided with the inner tube 8, which may be the ordinary draft tube, and with the outer tube 9 which is sustained by the member 10 of the lamp burner wall 11 and has the vertical slot 12. Shaft 13 is journaled in the lamp burner wall 11 and has the thumb nut 14, adapted to be operated to rotate said shaft 13 and the star wheel 15 which extends through said slot 12.

The tubes 8 and 9 are spaced apart to receive therebetween the wick A, of usual construction, and the wick carrier which latter comprises the annular member 16 having inwardly extending spurs 17, 17 to engage the wick A, and guides in which the rack plate 18 is adjustably secured. Preferably, the carrier 16 has the guide 20 one edge of which is spaced from the outer surface of said carrier to receive therebetween the rack plate 18. To some extent complemental to the guide 20, the guide and holding member 21 which is preferably of spring metal, is attached to the outer surface of carrier 16 and has the teeth 22 bent therefrom and adapted to enter the slots between the bars 19, 19 of rack plate 18 and to be received in the perforations 16, 16 of said carrier.

As shown in Fig. 1 the star wheel 15 is adapted, in its rotation, to engage the bars 19 of the rack member 18 to operate said rack 18 with its carrier 16 and the wick A to raise or lower said wick and the limit of said movement depends upon the length of the rack 18.

When the wick is consumed sufiiciently or to a predetermined point said wick and its carrier 16 are removed endwise from between the tubes 7 and 8, the holder or guide 22 springs out of engagement with the rack plate 18 and said rack plate can then be adjusted lengthwise and the parts replaced.

said tubes 8 and 9.

If desired the wick A may be disengaged fromthe spurs 17, 17 and moved lengthwise through said carrier to bring other portions of said Wick in position to be engaged by the spurs 17, 17 when said wick and its cary position between rier are again placed in By the use of this improved Wick carrier a much greater length of the Wick can be utilized than heretofore has been practicable. I v 7 Having thus described my invention I claim as new and desire to secure by Letters Patent- 1. A lamp burner comprisingan annular Wick carrier having guides and a spring clamp having teeth, and a rack plate slidably engaged with said guides and having meansadapted to'be engaged by the teeth of said clamp.

2. A lamp burner comprising an annular wick carrier having a pair of guides, a plate slidable in said guides relative to said carrier and having a series of transverse bars, and means carried by said carrier for engaging in the spacesbetWeen said bars.

3. A lamp burner comprising a pair of HERBERT F. MILLER.
